Problems solved by technology

[0005] In the above-mentioned large-scale magnetic resonance scanning technology, there are the following problems: (1) each positioning process is cumbersome and complicated, and it needs to rely on the operator's very rich operating experience to complete, and the scanning process consumes a lot of manpower; (2) even if it is completed for many However, there are differences in the scanned data of each segment, resulting in the stitching effect of the stitched image not being good enough, and even due to the deviation of the operating parameters in the positioning process, the result of the scan being completed but the stitching cannot be successful

Abstract

The embodiment of the invention discloses a magnetic resonance imaging method, a device thereof and equipment and a storage medium. The method comprises the following steps: 1, determining a preset scanning protocol according to a to-be-scanned part corresponding to a scanning object, wherein the preset scanning protocol comprises an overall protocol and at least two affiliated single bed protocols corresponding to the overall protocol, the overall protocol is associated with each corresponding affiliated single bed protocol through preset scanning parameters, the overall protocol is used forcontrolling overall scanning positioning of each bed, and the affiliated single bed protocols are used for controlling single bed scanning positioning of a single bed; adjusting at least one scanningparameter in the preset scanning protocol according to the scanning object information, and generating a target scanning protocol; and performing scanning positioning according to each overall protocol in the target scanning protocol, and performing magnetic resonance scanning on the target scanning protocol to generate a magnetic resonance image of the scanned object. By means of the technical scheme, the large-range magnetic resonance scanning protocol can be planned more efficiently, and the magnetic resonance imaging efficiency and the image splicing quality are improved.

Description

technical field [0001] Embodiments of the present invention relate to medical imaging technology, and in particular to a magnetic resonance imaging method, device, equipment and storage medium. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) technology is a widely used imaging diagnostic technology in clinical practice. It can accurately observe the size, shape and position of organs, and can display structures such as blood vessels and nerve fibers, so MRI can perform fine scans of the whole body. Large-scale body scans, such as whole-body diffusion-weighted imaging, whole-body vascular imaging, or whole-body spine imaging, can be used to obtain whole-body images in one scan for more comprehensive neurological disease diagnosis and tumor screening, which has very significant diagnostic value in clinical practice . [0003] Due to the physical limitations of the length of the magnet and the range of the gradient, the existing MRI ...
